Closer to home, Cuba was long coveted by Southerners as the choicest slave territory available. If annexed by the US and split into 3-4 states, it would restore the slave versus free state balance in Congress. President Polk had in 1845 offered the island’s owner, Spain, $100 million for the island, but it was refused and Madrid made it clear that they would not part with the island under any circumstance. Southerners were not about to give up their designs on Cuba, and several filibustering expeditions were mounted. They were easily repulsed by the Spanish authorities, and the last attempt ended in fifty Americans being captured and executed for piracy, including many men from the leading families of the South. A group of enraged Southerners responded by ransacking the Spanish consulate in New Orleans.
